This error seems to come from a different version of 'repo'. I use the 
one from the Chrome tools, not sure what this is using.

There may also be a misunderstanding. The Xtensa XTCC compiler chain is 
not directly available to the general public but only to Cadence 
licensees or Intel partners/customers for specific architectures. The 
exceptions are open platforms such as the MinnowBoard or SueCreek for 
which you can get the tools with a simple registration on the Cadence 
tools web site.

The 'repo' script is not going to provide you access to those tools, it 
only extracts GCC, firmware and Linux kernel.
